A robust optimization approach to wine grape harvesting scheduling

Hybrid modeling for vineyard harvesting operations

“…Workers skills in harvesting have a significant impact on the cost and efficiency of grape production, however it represents a critical source of variation (Ampatzidis and Whiting 2013). Various mathematical models have been developed to address the relation between the workers skills and the performance of harvesting and crop loss rates (Arnaout andMaatouk 2010, Bohle, Maturana, andVera 2010). However, many assumptions were applied that made the problem environment static, deterministic and deal with one single objective in most cases.…”

“…In addition, they can be used to quantitatively evaluate labor hiring policies and investigate their effect on vineyard operations. However, only few applications of such models have been described in the Mesabbah, Mahfouz, Ragab, and Arisha cultivating systems and in particular at vineyards operations (Ferrer et al 2008, Bohle, Maturana, andVera 2010).…”

Enhancing Eco-Efficiency of Agro-Products’ Closed-Loop Supply Chain under the Belt and Road Initiatives: A System Dynamics Approach

“…Pathumnakul et al [13] further considered the factors of technical maturity and seasonal market demands, in turn optimizing the supply chain of fresh shrimps in Thailand to minimize the storage cost. With regard to uncertainties in productivity, Bohle et al [14] applied robust optimization to the supply chain of wine grapes and developed an optimal grape harvesting scheduling. Similarly, Paksoy et al [15] considered production, transport capacity, and the uncertainties in market demand to optimize the edible vegetable oil supply chain.…”

Evaluation of Simulation-Based Optimization in Grafting Labor Allocation

“…Although these models have been utilized to consider the uncertainty rooted in demand, yield, or raw material in agricultural crops, to the best of our knowledge, no research has been conducted to study the impact of uncertainty caused by workers' performance, especially in a laborintensive horticultural operation like vegetable grafting. The application of optimization models utilized in different crops as noted has been less successful in this area due to its lack on capturing the uncertainty of the system and inherent complexity (Bohle et al, 2010). For example, modeling the growth of a plant as a closed-form equation in an optimization model is not easy.…”
